"The VLBA measurements, made in the spring and fall, allow the team to calculate distances to the stars and construct a map of the galaxy. The map’s accuracy, however, depends on comparing three sets of VLBA measurements taken over 18 months. Today’s shutdown of the National Radio Astronomy Observatory (NRAO), a National Science Foundation-funded organization that runs the radio telescopes, threatens that accuracy. “If you miss one of these observations, you basically have to start over the next season,” Reid says."
